Abstract: The invention consists of a particular wall, the use of which allows, together with all its own advantages of the so-called "traditional systems", which is to say of systems that foresee the on-site creation of the works planned, greater construction speed, typical of prefabricated systems, with a considerable savingof money and time.  With the use of the wall as of the invention it is possible to reduce the costs of building the structure, inclusive of the external curtain walls, by about 45% compared to a tunnel or load-bearing cut-off system and about 5% compared to the previous product called "partition panel" for the construction of structures made of reinforced concrete and curtain walls, as of the patent with record no. 45504/87 owned by the undersigned.  The field of use of the partition wall is that of the construction of buildings in general.  In buildings with a structure of reinforced concrete the said wall has a double function:-a) function of partitioning for the creation of the structures in reinforced concrete,-b) function of curtain walls for the said structures.  In buildings with load-bearing structures different from those in reinforced concrete the invention functions as a curtain wall.  In reinforced concrete buildings of the load-bearing cut-off type, the partition wall has the function of partitioning and at the same time thermal and acoustic insulation.The partition wall of the invention mainly comprises a single slab or two opposite slabs of suitable shape and dimensions.  In the case of two slabs, these can be connected to each other or they can be independent from each other and later made integral at the time of being put into operation by means of adjustable rigid systems, for the purpose of obtaining a product of suitable size.  Still in the case of two slabs, between these there can be a suitable gap for air or other material of the same nature or different from that forming the said slabs.  The slab(s) of the partition wall, which comprises (comprise) the partition of the structures made of reinforced concrete are of the disposable type and must possess suitable requisites of mechanical resistance and resistance to thermal conductivity.  One of the advantages deriving from the use of the partition wall of the invention is that of allowing the creation of curtain walls at the same time as creating the reinforced concrete structure, a curtain wall, which, given the material comprising the partition-slab(s), presents great resistance to thermal transmission and absolute elimination of cold bridges. Another particular characteristic of the invention is that of allowing the putting into operation inside the partition wall of all the technological installations belonging to building in general.  With the use of the partition wall a large part of the structural work necessary to create traditional structures in reinforced concrete of the framed type with girders and pillars is eliminated, since the particular shape of the invention allows the partitioning both of the pillars and of the girders in reinforced concrete.  Furthermore, in view of the considerable sound-proofing characteristics, mechanical resistance and lightness typical of the partition wall, it can be used, with the due shape and dimensions, as a partition or internal curtain wall for buildings in general.
